Abstract

Le domaine général de l'invention est celui des circulateurs et isolateurs hyperfréquences comportant trois voies métalliques (11, 12) disposées en Y et un noyau central (14) en ferrite. Au moins la partie centrale du substrat est un hexaferrite de baryum et /ou de strontium dont une partie des ions baryum et/ou une partie des ions strontium a été substituée par des ions lanthane et une partie des ions fer a été substituée par des ions cobalt, la formule chimique générale dudit hexaferrite de baryum-strontium étant BaxSryLazFe12-wCowO19, la somme des indices x, y et z étant égale à 1, l'indice x étant compris entre 0 et 1, l'indice y étant compris entre 0 et 1, l'indice z étant compris entre 0 et 0.5 et l'indice w étant compris entre 0.05 et 0.4.The general field of the invention is that of microwave circulators and isolators comprising three metal channels (11, 12) arranged in Y and a central core (14) in ferrite. At least the central part of the substrate is a barium and / or strontium hexaferrite in which a part of the barium ions and / or a part of the strontium ions has been replaced by lanthanum ions and a part of the iron ions has been substituted by ions cobalt, the general chemical formula of said barium-strontium hexaferrite being BaxSryLazFe12-wCowO19, the sum of the indices x, y and z being equal to 1, the index x being between 0 and 1, the index y being between 0 and 1, the index z being between 0 and 0.5 and the index w being between 0.05 and 0.4.
